Hello,
I am super-annoyed, since I have a patch on dvdnav, that I apply on all
VLC release, on Windows and Mac OS X, since (at least 2006).
I understand absolutely nothing of this obscure patch on this obscure
piece of code...
It does work quite, but I can't explain it, since it predates my work on
the project.
I thought I should share it, with you, upstream, as someone could make
some sense out of it.
With my best (sorry) regards
